Calculate the inductive reactance and the rms current in a similar circuit if the frequency is again 54.7 Hz, but the rms voltage is 80.9 V and the inductance is 47.8 mH.

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
